Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described further the utility model.
In conjunction with Fig. 1 to Fig. 5; The shell 1 of this spherical steam-water separator is a heavy wall steel shell; Be welded by two semicircular spherical sealings; The apparent size of housing and thickness design, check and make about the relevant criterion of steam boiler drum or pressurized container according to country according to the temperature and pressure parameter of institute's separate vapour.Offer personnel's access hole 2 on the top of this housing 1, its size need guarantee personnel's discrepancy and be convenient to installation, dismounting, inspection and the replacing of all parts in the separator.Consider that perforate will cause the part of casing rigidity and rigidity to weaken the sealing with the hole, according to the relevant criterion of steam boiler or pressurized container, this access hole opens the formula structure in adopting, and the housing around the hole is carried out reinforcement.Concrete structure is as shown in Figure 5, on access hole, establishes inner cap 46 and enclosing cover 48, and inner cap is connected through fixing bolt 47 with enclosing cover, and Sealing 50 is wherein arranged between inner cap and housing; On the housing of access hole periphery, set up and reinforce welding block 49.
At the inner cyclone separator 3 of installing of separator, its quantity is two to four, and it is divided into two groups by quantity, joins through two discrete each other steam inlet and external steam pipelines respectively.Steam pipe line is established three, and wherein steam pipe line 6 and 7 joins with two steam boilers respectively; Steam pipe line 27 is divided into two, converges the back with steam pipe line 6 and 7 respectively and joins with the steam inlet; Be equipped with control valve on each steam pipe line.The control valve 18 and 19 of 27 liang of branches of steam off pipeline is respectively separator by two steam boilers through steam pipe line 6 and 7 steam is provided, and its assignment of traffic can be regulated through control valve 16 and 17 respectively.Steam off pipeline 6 and 7 control valve are opened the control valve 18 and 19 of 27 liang of branches of steam pipe line simultaneously, and available separate unit steam boiler provides steam through steam pipe line 27 for separator.
The size of cyclone separator is considered the requirement of personnel through access hole according to JB/T9618-1999 " industrial boiler drum interior arrangement design criterion " and other the countries concerned's criterion calculation and design, the structural type that can adopt piecemeal to install.For preventing that the steam that bottom discharge is carried secretly from getting into water body, installs holder bucket 4 additional in the separator bottom.
For further improving the mass dryness fraction of steam, one group of corrugated sheet separator 5 is installed as the secondary separation element below steam (vapor) outlet, this separator is made up of polylith, fast demountable.
For preventing that too fast flow of steam from taking little water droplet out of steam (vapor) outlet pipeline 14, between cyclone separator 3 and corrugated sheet separator 5, install the removable even steam vent plate 24 of one deck additional.
Because salinity is high and water disturbance produces foam on liquid level, and one group of foam mechanism 25 that disappears is installed in the underwater in separator, this mechanism is made up of the orifice plate under water of a horizontal positioned and the orifice plate (not shown) of one group of radial setting layout in order to prevent.
For making the liquid level in the steam-water separator in normal range (NR), keep stable, to guarantee the proper functioning of cyclone separator, this steam-water separator is provided with fluid level control device.This device comprises a differential pressure transmitter 11, and differential pressure transmitter 11 high pressure sides and low voltage side are joined through last pressure inlet tube 8 and the housing of following pressure inlet tube 9 with steam-water separator respectively; Differential pressure transmitter 11 and an electric control valve 12 that is installed on the flowing line 10 are realized interlock.Differential pressure transmitter is measured the liquid level in the steam-water separator through the monitoring to differential pressure signal in good time, when liquid level surpasses last prescribing a time limit, through electric control valve 12 drain discharge is strengthened; When liquid level is lower than down in limited time, through electric control valve 12 drain discharge is reduced, make liquid level in a normal range (NR), keep stable.Because during the spheroid different heights, the volume flowrate that identical difference of liquid level is corresponding different, the aperture of electric control valve are calculated through pid algorithm according to liquid level signal and are confirmed.
Fluid level control device carries out the detection of liquid level in the spherical container with differential pressure method, to solve the problem of bringing owing to high temperature, high pressure steam that is difficult to accurate measurement.Before spherical shell puts into operation with being full of water in the upper and lower pressure inlet tube.The temperature difference of ignoring condensed water in the high and low side pressure inlet tube of differential pressure transmitter simultaneously, according to the hydrostatics principle, the liquid level differential pressure that differential pressure transmitter is measured is:
ΔP＝ρ1H1g-ρ2hg
In the formula, Δ P---differential pressure transmitter differential pressure value (kPa); ρ 1---the condensed water density (kg/m3) in the pressure inlet tube of transmitter high pressure side; The centre distance (m) of H1---the high and low side pressure inlet tube of separator; ρ 2---saturation water density (kg/m3) in the separator; H---saturation water liquid level (m).
Level Detection adopts programmable controller (PLC) as controller; The thermodynamic data of water and saturation water is arranged in the database of PLC; Call the linear interpolation instruction APR of PLC,, calculate the density of condensed water and saturation water according to detected separator pressure value; The above-mentioned formula of substitution calculates behind pressure compensation saturation water liquid level in the separator, and the PID through the saturation water liquid level regulates the efficient operation that can realize separator.
Probe tube 26 is installed on steam-water separator steam (vapor) outlet pipeline 14.Probe tube is connected with steam sampling device 20, and the steam sampling device is made up of sample collector 45, sampling discharge tube 44 and sampling modulating valve 43.Can carry out sample analysis to the steam (vapor) outlet mass dryness fraction through sampler.In the steam-water separator case top safety valve 15 and pressure gauge 23 are installed.In the housing minimum point sewage draining exit 21 is installed.
